2 Claims. (Cl. 175-41) The invention relates more particularly tocondensers of the tubular type, that is where the active condenserelements are enclosed within a hollow or tubular insulating casing, andaims pari 5 ticularly to provide a. simple and economical constructionof the above character wherein wire terminals are employed. Furtherobjects and advantages of the invention will be in part obvious and inpart specifically pointed out in the descripl tion hereinafter containedwhich, taken in conjunction with the accompanying drawing, discloses apreferred embodiment of the invention; such embodiment, however, is toberegarded as merely illustrative. In the drawing- ,i

Fig. 1 is a longitudinal section showing the internal parts of acondenser made in accordance with the invention.

Fig. 2 is a longitudinal section of the complete device and Fig. 3 is across Sectional vietg'taken on the central portion of Fig. 2. v

The invention is illustrated as applied to a condenser having aninsulating base member l, which carries dielectric strips 2 andconducting strips 3 and 4 respectively, which are of opposite polarity.The strips 2, 3 and 4, for example, may be wound or rolled about theinsulating member 1.

'I'he conducting strips 3 have portions 5 which extend beyond one edgeof the dielectric sheets 2, at one end of the insulating member 1, andthe conducting strips 4 have similar extending portions 6 at theopposite end of member 1.

The parts of the condenser above described are enclosed Within a tubularinsulating casing 7, as shown in Figs. 2 and 3, and wire terminals 8extend outwardly through the opposite ends of casing 7, these terminalsbeing bendable in all directions but sufciently stiii' to support thecondenser in any desired position.

The inner ends of the terminals 8 are mechanically clamped against theextending portions and 6 of the supporting strips; as shown rivets oreyelets 9 respectively extend through the opposite end portions of theinsulating member 1, and the extending portions 5 and 6 of theconducting strips, these rivets being headed over to hold the terminals8 in good electrical contact with the conducting strips. Preferably theterminals 8 are also interengaged with the respectively adiacentportions of the insulating member 1, to assist in keeping them in properposition. As shown at the right of Fig. 1, terminal 8 may be passedthrough an opening 10 in the insulating member 1 for this purpose, ormay be coiled around the adjacent portion of the insulating member 1, as

Vjacent portions of said first mentioned insulating Vof Figs. 1 and 2.

Preferably the ends of insulating casing 'I are closed by fasteners 12,as shown in Fig. 2, and the space within the casing '7 may be filledwith 60 suitable insulating composition 13 (Fig. 3).

While a specfic embodiment of the invention has been described, itshould be understood that changes may be made therein, without departingfrom the invention, within the scope of the appended claims. 1

I claim:
